In this article, we show that rotation of a black hole can create antigravity and anti-gravitational waves, given that there is a strong gravity in the black hole, which distorts time and space. At first, we derived the curvature tensors upon Einstein’s field equation, using spherical polar coordinates, and then calculated the coefficients of the curvature tensors to simulate the strength of each component of the tensors. It is assumed that the stress-energy tensor, which is located outside of the black hole, can reflect the strength of the gravitational field and the gravitational waves. As the result, we concluded that, if the time and space are distorted in the black hole, the rotation can create antigravity and the anti-gravitational waves. In addition, the result of the simulation shows that the antigravity positively contributes to the stress-energy tensor, which may expand the size of the Universe.
